The electronic structure of the isostructural rare‐earth systems TmGa 3 , ErGa 3 , and CeIn 3 has recently been investigated by measurements of two‐dimensional angular correlations of annihilation radiation (2D ACAR). We employ different tomography techniques to reconstruct electron‐positron (e‐p) momentum density ρ ( p ) from its line projections. In all these compounds we get very specific shape of ρ ( p ). In order to draw the Fermi surface (FS), we perform conversion from the extended p to reduced k space. In the case of TmGa 3 and ErGa 3 a nesting feature of the FS consistent with the antiferromagnetic structure is observed. On the other hand, in CeIn 3 we cannot detect any link between the FS topology and the vector of the magnetic propagation. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
